Sliding roof system

Abstract

A sliding roof system includes at least one guide rail, a carriage shiftable in the guide rail, and a cover support coupled with the carriage. The cover support is adapted to be attached to a cover that is movable to open and close a roof opening. A first lifting lever has one end connected to the cover support and another end connected to the carriage with guide pieces received within slots formed in the carriage.

1. A sliding roof system comprising:
 at least one guide rail; 
 a carriage shiftable in the at least one guide rail; 
 a cover support adapted for attachment to a cover, the cover support being coupled with the carriage; 
 a first lifting lever having one end connected to the cover support and another end connected to the carriage with first and second guide pieces that are movable relative to the carriage; and 
 a second lifting lever having one end connected to the cover support, and another end connected to the carriage with third and fourth guide pieces. 
 
     
     
       2. The sliding roof system according to  claim 1  wherein the cover support is in engagement with a guiding slot fanned in the at least one guide rail. 
     
     
       3. The sliding roof system according to  claim 2  wherein the cover support is in direct engagement with the guiding slot via at least one pin. 
     
     
       4. The sliding roof system according to  claim 2  wherein the cover support is coupled to the guiding slot with a guiding lever. 
     
     
       5. The sliding roof system according to  claim 4  wherein the guiding lever converts travel of the guiding slot into greater travel of the cover support. 
     
     
       6. The sliding roof system according to  claim 1  wherein a distance between the first and second guide pieces is less than half an overall length of the first lifting lever. 
     
     
       7. The sliding roof system according to  claim 1  wherein the carriage includes at least one lifting slot and wherein at least one of the first and second guide pieces comprises a pin supported by the first lifting lever that engages into the at least one lifting slot. 
     
     
       8. The sliding roof system according to  claim 7  wherein the at least one lifting slot comprises first and second lifting slots and wherein the first lifting lever engages into the first and second lifting slots. 
     
     
       9. The sliding roof system according to  claim 7  wherein the second lifting lever is in engagement with at least one lifting slot. 
     
     
       10. A sliding roof system comprising:
 at least one guide rail; 
 a carriage shiftable in the at least one guide rail wherein the carriage includes a front carriage part and a rear carriage part that are pivotally connected to each other; 
 a cover support adapted for attachment to a cover, the cover support being coupled with the carriage; and 
 a first lifting lever having one end connected to the cover support and another end connected to the carriage with first and second guide pieces that are movable relative to the carriage. 
 
     
     
       11. The sliding roof system according to  claim 1  wherein the cover includes a first cover portion and a second cover portion, the first cover portion being movable to lie above the second cover portion. 
     
     
       12. The sliding roof system according to  claim 1  wherein the carriage includes a plurality of lifting slots including a first lifting slot and a second lifting slot, the first guide piece being received within the first lifting slot and the second guide piece being received within the second lifting slot. 
     
     
       13. A sliding roof system comprising:
 at least one guide rail; 
 a carriage shiftable in the at least one guide rail; 
 a cover support adapted for attachment to a cover, the cover support being coupled with the carriage; 
 a first lifting lever having one end connected to the cover support and another end connected to the carriage with first and second guide pieces that are movable relative to the carriage, and wherein the carriage includes a plurality of lifting slots including a first lifting slot and a second lifting slot, the first guide piece being received within the first lifting slot and the second guide piece being received within the second lifting slot; and 
 a second lifting lever having one end connected to the cover support and another end connected to the carriage by third and fourth guide pieces wherein the plurality of lifting slots includes a third lifting slot, the third and fourth guide pieces being received within the third lifting slot. 
 
     
     
       14. The sliding roof system according to  claim 13  wherein the first and second guide pieces comprise first and second guide pins provided on the first lifting lever and wherein the third and fourth guide pieces comprise third and fourth guide pins provided on the second lifting lever. 
     
     
       15. The sliding roof system according to  claim 13  wherein the first guide piece is movable within the first lifting slot, the second guide piece is movable within the second lifting slot, and the third and fourth guide pieces are movable within the third lifting slot to move the cover between open and closed positions.
